- The fourth object of the inventionis the production' of posts, columns, picrsof concrete and the like with metal jackets.

' In the accompanying drawing Fig. l represents a vertical section as on the line. I, 'I', of Fig. 2 of averticaltier of molds for a post, column, pi'erE'and the like for concrete, cement, and the like: Fig. 2* shows a top view of the upper portionof Fig. 1. Fig. 3 represents a fragmentary upper portion of Fig. l filled with concrete; Fig. 4 indicates: a right hand view of Fig. 3; Fig. 5 isa section of- Fig. I on the line 5, 5; Fig. 6 represents a section of Fig. l on the line 6, 6; 'Fig. 'l-shows a pair of postswith their tiers of molds, and a lattice connecting'them all in position for use, and Fig. 8 indicates a modificationof the molds.

The tiers of the molds in this instance of'sheet metal are indicated having three members. The topmember of the tier is designated in its entirety by' the numeral 20, the middle member is shown at 50' and the bottom member is shown at 10. All of the members are made of one piece of material which may be steel, iron and the like.

The'top member 2|] in this instance is square in cross-section and comprises the front wall 22, therear wall. 23 and the side walls 24 and 25. The top edges of the walls of the member are indicated at 26 and their lower edges are shown at 21. The rear wall 23 has integral therewith the longitudinal outwardly extending flange 29 at right angles thereto. The side wall has a laps the flange 29. Bolts 32 connect the flange 29' and. the overlapped portion 30. A bolt 33 having the nut 34 extends from the wallj25, to secure a lattice to be described in place. An open- 55 ing' 35 having the bottom edge 36 and'the verlongitudinal? extending portion 30', which overtical edges 31 extend downwardly from the top edge 26 'of the wall 22. A chute is designated in its entirety by the numeral 40. The said chute comprises the inclined wall 4| with the depending' flange42 at its lowerend and the side walls '43 extending up from the inclined wall 4|. Each of the side walls hasintegral therewith the flange 44 at right angles thereto. A strut 45 has integral therewith at its lower end the foot 46 and its upper end is fastened to the wall 4| by the rivet 41. When the tier of molds is to be charged with its concrete 48 or other plastic material, the chute 40 is placed in position by moving the flange 42 through the opening 35 and supporting the upper end of the latter upon the bottom edge 36 of the said opening 35. The flanges 44 and thefoot 46 are positioned-to bear against the outer face of the front wall' 22. A closing plate 49 is provided for the opening 35. The middle member 50 of thetier in this instance is also square in crosssection and comprises the front wall 52, the rear wall 53, the side wall 54, and the side wall having the portions and 56. The portion 55 has integral therewith the inwardly extending longitudinal flange 58 at right angles thereto. The portion 56 has integral therewith the inwardly extending U shaped longitudinal flangeg60, which is locked with the flange 58. A bolt 6 I with a nut and similar to 33 extends from the wall 55. The top edges of the walls of the member 54 are indicated at 62- and the bottom edges are indicated at 63.

j The bottom portion of the member 20 is in adjustable collapsible relation with the top portion of the member 50, by inserting the latter portion into the former. Wedges 64 having the heels 64a are adjustably inserted between the top portion of the member 50 and the lower portion of the member 20 to lengthwise adjustably lock them in position.

, The bottom portion of the member 50 is in adjustable collapsible relation with the bottom member 10, by inserting said bottom portion into the top portion of said member 10. Wedges 68 having the heels 68a. are adjustably inserted between the bottom-portion of the member 56 and the op portion of the member 10 to lengthwise adjustably lock them in position.

Thebottom member 10 of the tier is constructed as described for the member 20, but the opening 35 is omitted. The said memberlil' is also square in cross-section, and" comprises the front wall 12, the rear wall 13withthe longitudinal outwardly extended flange 14*, the side wall 15 and the side Wall 76 With the longitudinal extending portion TI, which latter overlaps the flange I4. Bolts 18 connect the flange I4 and the portion TI. The top edges of the walls of the member I0 are indicated at 19 and their lower edges are indicated at 80. A bolt BI with the nut 8 la is provided for the wall I6.

The lower edges of the member 10, see Fig. 1, are supported on a foundation 82, comprising a block of concrete positioned in the ground 83.

Referring to Fig. 7, a pair of posts are indicated with their tiers of molds. The latter comprise for each tier, the top member 20, the middle member 50 and the bottom member I0, connected in place by means of the keys 64 and 68. The bottom edge 80 of each member I0 bears upon a foundation block 82 as already described, and which latter is somewhat below the surface of the ground 83. Between the tiers of the posts is indicated a lattice frame 90. The said frame comprises the top member 9I, the bottom member 92 and the vertical members 93. To the front faces of the members of said frame are fastened the slats and 96, which constitute the lattice of the frame. The vertical walls 93 of the lattice frame are positioned between the tiers of the molds and are fastened to the side wall 25, the portion 55 and the wall I6 of the molds by the bolts 33, 6| and BI. Each of the tiers of molds is charged with its concrete by pouring the same therein, by means of the chute 40. When the concrete is up to the level of the bottom edge 36 of the opening 35 of the top member 20, the chute 40 is removed and the closing plate 49 is placed in position to close the opening 35. Next the top member 20 is charged with the concrete up to the top edges of its walls.

Referring to Fig. 8, there is shown a top View of a pair of modified molds. In this modification the top member of the tier which is cylindrical in cross-section is indicated at I00. The said top member which is also made of a plate of sheet metal has extending from its longitudinal edges the flanges I02. The said flanges are clamped to each other by bolts I03, one of which is shown. An opening I05 similar to 35 extends from the top edge of the member I00, and for which is provided a closing plate I06, similar to 49.

The middle member of the tier in this modification is shown at I I0, and is also made of a plate of sheet metal. One end of the member IIO has integral therewith the inwardly extending longitudinal flange I I2, and its other end has integral therewith the inwardly extending U shaped longitudinal flange I I 3, which latter is locked with the flange II 2. Bolts II5, similar to 33 extend from the walls of the molds to clamp a lattice frame as shown in Fig. '7 in place.

In the modification shown in Fig. 8, the members of the mold are positioned in collapsible relation and are detachably connected together by keys as shown in Fig. 1.

In the drawing the tiers are indicated each with three molds, but it will be understood that each tier may comprise only one or two molds or more than three.

It will also be noted that when three molds comprise a tier, that the cross section of the middle member is smaller than the cross-section of the top member and the cross-section of the bottom member. It will be noted further that the connecting means for the walls of the mold of the middle member are within the same and that the connecting means for the walls of the molds of the top and bottom members are on the outside thereof.

It will be noted further that the tiers of molds with their concrete and the like constitute posts, columns and piers of concrete and the like with metal jackets. It is also to be noted that when the concrete in the tiers has hardened that the wedges connecting the molds are removed. By means of the heels of the wedges the latter can be easily inserted between the molds or detached therefrom.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.

Having described my invention, I claim:

1. The combination of a tier of molds, the crosssection of one mold greater than the cross-section of the mold next adjacent, each mold consisting of a plate of sheet material shaped to requisite form, the ends of the sheets of material of the larger molds extending outwardly, means to connect said ends, the end of the sheets of material of the smaller molds extending inwardly and locked to each other, the smaller molds having their end portions extending into the end portions of the larger molds, and means to adjustably connect the ends of the smaller molds to the ends of their adjacent larger molds.
